Make a bendable/posable 2d person
You could do it several ways I guess. Here is one (but sorry I won't go too much in details). There are 2 aspects, the rigging and the face animations:


Create your mesh, give it enough geometry so that you will be able to bend it, if you're using a Subdivision Surface modifier of course it would need additional edge loops.





You could directly parent your object to an armature, it really depends on the deformation you'll need. If it doesn't work smoothly you may prefer to use a Mesh Deform modifier: Create a sort of cage that will encompass your character. Give it a bit of subdivisions. Make it invisible in Render mode. Give your character a Mesh Deform modifier and Bind it to the cage.





Parent this cage to an armature, maybe choose Bendy Bones so that the bones bend smoothly (not sure it's useful for a simple mesh though).





For the face animation you could use the UV Warp modifier as explained for example here by BornCG. This is the cleanest way to do it. A simpler way would be first to create an image with all your different facial expressions then create one UV map by expression:





Then to switch from an expression to another, use a Mix Shader that will switch from a UV map to another:
